Geographic distribution limits of organisms are often affected by climate, but little is known of how the impacts of climate evolve within sets of related taxa. Here we identified the climate variables most closely associated with low‐elevation limits, optimal elevations, and high‐elevation limits of plant species’ distributions and compared evolutionary lability of niche values predicting the three aspects of distribution best.

是什么驱动物种沿着海拔梯度分布？来自阿尔卑斯山中部十字花科的宏观生态学和进化见解

生物的地理分布范围通常受气候影响，但人们对气候的影响如何在一组相关的分类单元内演化知之甚少。在这里，我们确定了与植物物种分布的低海拔限度，最佳海拔和高海拔限度最密切相关的气候变量，并比较了利基值的进化不稳定性预测了分布的三个方面。
